We present the numerical simulations for an electron-beam-driven and loss-cone-driven electron cyclotron maser (ECM) with different plasma parameters and different magnetic field strengths for a relatively small region and short time-scale in an attempt to interpret the recent discovered intense radio emission from ultracool dwarfs. ... A wide frequency band should therefore be covered by future radio observations. ...
